Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.

Heat pump installation,
planned properly.
A heat pump replaces a furnace and AC with one system for heating and cooling. Good results come from sizing, layout and electrical planning done before equipment is ordered.
Ducted or ductless
Keep existing ducts when they are in good shape, or go ductless where ducts are missing, leaky or impossible to run.
Electrical capacity check
HAXX electricians review the panel and service before the install, so a surprise panel upgrade does not appear mid-project.
Brands we install
Mitsubishi Electric and American Standard systems, among others, matched to the home and budget.
Permits and inspection
HAXX pulls the mechanical and electrical permits and meets the city inspector.
Rebate paperwork
We point you to the rebates your address qualifies for and provide the equipment documentation programs ask for.
SOUTH SAN FRANCISCO DETAILSBefore you install
Before you install
a heat pump in South City.
South San Francisco's 2021 reach code requires all-electric new homes, while existing homes can still choose. Many owners switch when an old furnace fails.
01
Sized for a mild, windy climate
Heating is the main load in most South City homes. HAXX runs a room-by-room load calculation instead of matching the old furnace size.
02
Postwar homes
Buri Buri, Winston Manor and Westborough grew after World War II. Original duct runs are inspected for leaks and size before a ducted heat pump goes in.
03
Utility programs
Homes here get power from WestLight Energy (formerly Peninsula Clean Energy), with PG&E delivery. WestLight lists heat pump rebates; confirm eligibility directly with WestLight Energy.

GOOD TO KNOW
Heat Pump Installation in South San Francisco: questions, answered.
Does South San Francisco require a heat pump in an existing home?
No citywide rule requires it for a simple equipment swap. The 2021 reach code targets new construction and major renovations that replace over half of the foundation or framing.
Is a permit needed for a heat pump in South San Francisco?
Yes. Mechanical and electrical work is permitted through the City's online portal at permits.ssf.net. HAXX applies and meets the inspector.
Can a heat pump heat my house on cold nights?
Yes. Bay Area winters are mild, and correctly sized heat pumps heat comfortably through them. Sizing and duct condition matter more than the brand.
How long does an installation take?
Most single-system replacements take one to three days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
